The IBM Storage product portfolio includes disk , flash , tape , NAS storage products, storage software and services. IBM's approach is to focus on data management.
63-456: The IBM DS8000 series (early IBM System Storage DS8000 series) is an IBM storage media platform with hybrid flash and hard disk storage for IBM mainframes and other enterprise grade computing environments. This series was formerly designed as a line of cabinet-size solutions, prior to the more compact and affordable rack-mount DS6000 series. In 2015 the DS6000 line were discontinued, and
126-553: A road case approved by the Air Transport Association of America (ATA), sometimes also referred to as a flight case . Road cases typically have plywood sides laminated with polyvinyl chloride (PVC), extruded aluminum edges, steel corners, handles, and latches. Larger cases typically have wheels for easy transport. Road case racks come in different heights based on the 1U standard and different depths. Non-isolated cases simply mount 19-inch mounting posts inside
189-498: A 1.5U server or devices that are just 22.5 or 15 cm in width, allowing for 2 or 3 such devices to be installed side by side, but these are much less common. The height of a rack can vary from a few inches, such as in a broadcast console, to a floor-mounted rack whose interior is 45 rack units (200.2 centimetres or 78.82 inches) high. 42U is a common configuration. Many wall-mounted enclosures for industrial equipment use 19-inch racks. Some telecommunications and networking equipment
252-485: A 19-inch rack. With the prevalence of 23-inch racks in the Telecoms industry, the same practice is also common, but with equipment having 19-inch and 23-inch brackets available, enabling them to be mounted in existing racks. A key structural weakness of front-mounted support is the bending stress placed on the mounting brackets of the equipment, and the rack itself. As a result, 4-post racks have become common, featuring
315-568: A Stretched Cluster Mode, with automatic fail over between two data centers, and can have SSD that can be used by EasyTier software to perform sub-LUN automatic tearing. IBM Spectrum Control provides infrastructure management for virtualized, cloud and software-defined storage. IBM Spectrum Protect is a progression of the Tivoli Storage Management product. IBM Spectrum Archive allows users to run any application designed for disk files against tape data without concern for
378-412: A cubic meter. Newer server rack cabinets come with adjustable mounting rails allowing the user to place the rails at a shorter depth if needed. There are a multitude of specialty server racks including soundproof server racks, air-conditioned server racks, NEMA-rated, seismic-rated, open frame, narrow, and even miniature 19-inch racks for smaller applications. Cabinets are generally sized to be no wider than
441-978: A gap of 17.75 inches (450.85 mm), giving an overall rack width of 19 inches (482.60 mm). The posts have holes in them at regular intervals, with both posts matching, so that each hole is part of a horizontal pair with a center-to-center distance of 18.312 inches (465.12 mm). The holes in the posts are arranged vertically in repeating sets of three, with center-to-center separations of 0.5 inches (12.70 mm), 0.625 inches (15.88 mm), 0.625 inches (15.88 mm). The hole pattern thus repeats every 1.75 inches (44.45 mm). Holes so arranged can either be tapped (usually 10-32 UNF thread, or, less often, 6mm metric ) or have square holes for cage nuts . Racks are vertically divided into regions, 44.45 millimetres (1.75 in) in height. Each region has three complete hole pairs on each side. The holes are centered at 6.35 millimetres (0.25 in), 22.25 millimetres (0.88 in), and 38.15 millimetres (1.50 in) from
504-474: A mirrored pair of rear mounting posts. Since the spacing between the front and rear mounting posts may differ between rack vendors and/or the configuration of the rack (some racks may incorporate front and rear rails that may be moved forwards and backward, e.g. APC SX-range racks), it is common for equipment that features 4-post mounting brackets to have an adjustable rear bracket. Servers and deep pieces of equipment are often mounted using rails that are bolted to
567-964: A price point somewhat closer to tape media. Supported on-premise datastores include IBM Cloud Object Store (aka Cleversafe) and IBM Spectrum Scale object. Off-premise datastores would be popular S3-compatible cloud services like IBM Bluemix (aka Cleversafe cloud).

These cases are marketed to musicians and entertainers for equipment not subject to frequent transportation and rough handling. The polyethylene shell is not fiberglass reinforced and is not rigid. The shape of small cases is maintained by the rack rails and the cover seal extrusions alone. Larger cases are further reinforced with additional plywood or sheet metal. The outer shell
819-489: A second life to previous-generation storage systems. Modern virtualization functions like inline real-time compression for data on external systems can help delay capacity repurchase for several years. Transparent Cloud Tiering for Swift- and S3-compatible object datastores can be used as a cold tier for incremental volume snapshots and volume archives without live production access. This allows keeping hourly time machine copies or archiving VM images including attached volumes at
882-546: A wider folded strip arranged around the corner of the rack. The posts are usually made of steel of around 2 mm thickness (the official standard recommends a minimum of 1.9 mm), or of slightly thicker aluminum . Racks, especially two-post racks, are often secured to the floor or adjacent building structure so as not to fall over. This is usually required by local building codes in seismic zones . According to Telcordia Technologies Generic Requirements document GR-63-CORE, during an earthquake, telecommunications equipment
945-435: Is h = 1.75 n − 0.031 for calculating in inches, and h = 44.45 n − 0.794 for calculating in millimeters. This gap allows a bit of room above and below an installed piece of equipment so it may be removed without binding on the adjacent equipment. Originally, the mounting holes were tapped with a particular screw thread. When rack rails are too thin to tap, rivet nuts or other threaded inserts can be used, and when
1008-401: Is industrial power, control, and automation hardware . Typically, a piece of equipment being installed has a front panel height 1 ⁄ 32 inch (0.031 in; 0.79 mm) less than the allotted number of Us. Thus, a 1U rackmount computer is not 1.750 inches (44.5 mm) tall but is 1.719 inches (43.7 mm) tall. If n is number of rack units, the ideal formula for panel height

IBM TS4300 enhanced modern data protection helps meet security and compliance requirements. The IBM® TS2900 Tape Autoloader
1197-413: Is a large number of computers in a single rack, it is impractical for each one to have its own separate keyboard, mouse, and monitor. Instead, a KVM switch or LOM software is used to share a single keyboard/video/mouse set amongst many different computers. Since the mounting hole arrangement is vertically symmetric, it is possible to mount rack-mountable equipment upside-down. However, not all equipment
1260-561: Is a range of dedicated, non-SSD "all-flash" storage systems, based on a Intel x86 platform. IBM acquired flash storage system maker Texas Memory Systems in 2012. In April 2013, IBM announced a plan for a $ 1 billion investment in flash storage research and development, and then the product line-up was renewed in 2014 with the announcement of the FlashSystem 840 and FlashSystem V840. IBM has been updating these models every year. The former IBM FlashSystem had 1U-size solutions only, but
1323-562: Is a standardized frame or enclosure for mounting multiple electronic equipment modules. Each module has a front panel that is 19 inches (482.6 mm) wide. The 19 inch dimension includes the edges or ears that protrude from each side of the equipment, allowing the module to be fastened to the rack frame with screws or bolts. Common uses include computer servers , telecommunications equipment and networking hardware , audiovisual production gear, professional audio equipment, and scientific equipment .

IBM® TS4300 Tape Library
1638-411: Is frequently embossed in a self-mating pattern to combat the tendency for stacked cases to deform slightly creating a slope that encourages the upper case to slide off. The cases typically use extruded aluminum bands at the ends of the body with tongue-and-groove mating to like bands for the covers. End covers are typically secured with either a simple draw latch or a rotary cam butterfly latch, named for
1701-435: Is mounted via rails (or slides). A pair of rails is mounted directly onto the rack, and the equipment then slides into the rack along the rails, which support it. When in place, the equipment may also then be bolted to the rack. The rails may also be able to fully support the equipment in a position where it has been slid clear of the rack; this is useful for inspection or maintenance of equipment which will then be slid back into
1764-641: Is still used in legacy ILEC / CLEC facilities. Nineteen-inch racks in two-post or four-post form hold most equipment in enterprise data centers , ISP facilities, and professionally designed corporate server rooms , although hyperscale computing typically use wider racks. They allow for dense hardware configurations without occupying excessive floor space or requiring shelving. Nineteen-inch racks are also often used to house professional audio and video equipment, including amplifiers , effects units , interfaces, headphone amplifiers, and even small-scale audio mixers. A third common use for rack-mounted equipment
1827-409: Is subjected to motions that can over-stress equipment framework, circuit boards, and connectors. The amount of motion and resulting stress depends on the structural characteristics of the building and framework in which the equipment is contained and the severity of the earthquake. Seismic racks rated according to GR-63 , NEBS Requirements: Physical Protection, are available, with Zone 4 representing
1890-400: Is suitable for this type of mounting. For instance, most optical disc players will not work upside-down because the driving motor mechanism does not grip the disc. 19-inch server racks can vary in quality.

The software offers simple management with monitoring and reporting capabilities, including storage usage by user and group definitions. The Active Cloud Engine (ACE)
2394-602: The fans. However, some rack equipment has been designed to make fan replacement easy, using quick-change fan trays that can be accessed without removing the cabling or the device from the rack, and in some cases without turning off the device so that operation is uninterrupted during replacement. The formal standards for a 19-inch (482.6 mm) rack are available from the following: A rack's mounting fixture consists of two parallel metal strips (also referred to as posts or panel mounts ) standing vertically. The posts are each 0.625 inches (15.88 mm) wide, and are separated by
2457-594: The front and exhaust on the rear. This prevents circular airflows where hot exhaust air is recirculated through an adjacent device and causes overheating. Although open-frame racks are the least expensive, they also expose air-cooled equipment to dust, lint, and other environmental contamination. An enclosed sealed cabinet with forced air fans permits air filtration to protect equipment from dust. Large server rooms will often group rack cabinets together so that racks on both sides of an aisle are either front-facing or rear-facing, which simplifies cooling by supplying cool air to
2520-423: The front and rear posts (as above, it is common for such rails to have an adjustable depth), allowing the equipment to be supported by four posts, while also enabling it to be easily installed and removed. Although there is no standard for the depth of equipment, nor specifying the outer width and depth of the rack enclosure itself (incorporating the structure, doors and panels that contain the mounting rails), there

2646-485: The minimum bend radius for fiber and copper cables) and deeper equipment to be utilized. A common feature in IT racks is mounting positions for zero-U accessories, such as power distribution units (PDUs) and vertical cable managers and ducts, that utilize the space between the rear rails and the side of the rack enclosure. The strength required of the mounting posts means they are invariably not merely flat strips but actually
2709-465: The most demanding environment. GR-3108 , Generic Requirements for Network Equipment in the Outside Plant (OSP), specifies the usable opening of seismic-compliant 19-inch racks. Heavy equipment or equipment that is commonly accessed for servicing, for which attaching or detaching at all four corners simultaneously would pose a problem, is often not mounted directly onto the rack but instead
2772-653: The particular class of equipment to be mounted is known in advance, some of the holes can be omitted from the mounting rails. Threaded mounting holes in racks where the equipment is frequently changed are problematic because the threads can be damaged or the mounting screws can break off; both problems render the mounting hole unusable. Tapping large numbers of holes that may never be used is expensive; nonetheless, tapped-hole racks are still in use, generally for hardware that rarely changes. Examples include telephone exchanges, network cabling panels, broadcast studios and some government and military applications. The tapped-hole rack
2835-523: The posts and allow the rack to be securely attached to the floor and/or roof for seismic safety. Equipment can be mounted either close to its center of gravity (to minimize load on its front panel), or via the equipment's front panel holes. The Relay Racks name comes from early two-post racks which housed telephone relay and switching equipment. Two-post racks are most often used for telecommunication installations. 19-inch equipment that needs to be moved often or protected from harsh treatment can be housed in
2898-418: The rack. Some rack slides even include a tilt mechanism allowing easy access to the top or bottom of rack-mounted equipment when it is fully extended from the rack. Slides or rails for computers and other data processing equipment such as disk arrays or routers often need to be purchased directly from the equipment manufacturer, as there is no standardization on such equipment's thickness (measurement from

A variety of airflow patterns can be found, including front intakes and rear exhausts, as well as side intakes and exhausts. Low-wattage devices may not employ active cooling, but use only passive thermal radiation and convection to dissipate heat. For rack-mounted computer servers, devices generally intake air on
3087-407: The side of the rack to the equipment) or means for mounting to the rail. A rails kit may include a cable management arm (CMA), which folds the cables attached to the server and allows them to expand neatly when the server is slid out, without being disconnected. Computer servers designed for rack-mounting can include a number of extra features to make the server easy to use in the rack: When there
3150-461: The square-hole rack. Square-hole racks allow boltless mounting, such that the rack-mount equipment only needs to insert through and hook down into the lip of the square hole. Installation and removal of hardware in a square-hole rack is very easy and boltless, where the weight of the equipment and small retention clips are all that is necessary to hold the equipment in place. Older equipment meant for round-hole or tapped-hole racks can still be used, with
3213-618: The standard 24-inch-wide (610 mm) floor tiles used in most data centers. Racks carrying telecom equipment like routers and switches often have extra width to accommodate the many cables on the sides. Four-post racks allow for mounting rails to support the equipment at the front and rear. These racks may be open in construction without sides or doors or may be enclosed by front and/or rear doors, side panels, and tops. Most data centers use four-post racks. Two-post racks provide two vertical posts. These posts are typically heavy gauge metal or extruded aluminum. A top bar and wide foot connect

3339-472: The technology that is mounted within it has changed considerably and the set of fields to which racks are applied has greatly expanded. The 19-inch (482.6 mm) standard rack arrangement is widely used throughout the telecommunications , computing , audio , video , entertainment and other industries, though the Western Electric 23-inch standard , with holes on 1-inch (25.4 mm) centers,
3402-556: The top or bottom of the region. Such a region is commonly known as a U , for unit , RU for rack unit or, in German, HE , for Höheneinheit . Heights within racks are measured by this unit. Rack-mountable equipment is usually designed to occupy some integer number of U. For example, an oscilloscope might be 4U high. Rack-mountable computers and servers are mostly between 1U and 4U high. A blade server enclosure might require 10U. Occasionally, one may see fractional U devices such as
3465-400: The underfloor space to the underside of enclosed rack cabinets. A difficulty with forced air fan cooling in rack equipment is that fans can fail due to age or dust. The fans themselves can be difficult to replace. In the case of network equipment, it may be necessary to unplug 50 or more cables from the device, remove the device from the rack, and then disassemble the device chassis to replace
3528-428: The use of cage nuts made for square-hole racks. Rack-mountable equipment is traditionally mounted by bolting or clipping its front panel to the rack. Within the IT industry, it is common for network/communications equipment to have multiple mounting positions, including tabletop and wall mounting, so rack-mountable equipment will often feature L-brackets that must be screwed or bolted to the equipment prior to mounting in
3591-638: The world of telephony . By 1911, the term was also being used in railroad signaling . There is little evidence that the dimensions of these early racks were standardized. The 19-inch rack format with rack-units of 1.75 inches (44.45 mm) was established as a standard by AT&T around 1922 in order to reduce the space required for repeater and termination equipment in a telephone company central office . The earliest repeaters from 1914 were installed in ad hoc fashion on shelves, in wooden boxes and cabinets. Once serial production started, they were built into custom-made racks, one per repeater. But in light of

The last XIV Gen3 model offers 2, 3, 4 or 6 TB drives, providing up to 485 TB of usable capacity per rack. SSD caching (available as an option) adds up to 12 TB of management-free high-performance data caching capability to the entire array. The system can also connect to external storage via Fibre Channel (8 Gbit/s) and iSCSi (1 or 10 Gbit/s). The XIV line
